HEATING APPARATUS Filed April 22, 1929 INVENTOR ZW ATTORNEY n Patented May 5, 1931 PATENT; OFFICE CBENO B r R A L QWN. fIbwA HEATING rremr s l pplication filed. April 22,

My invention relatestofimprov'ements in heating means for brooders and hovers, and the objects of my improvement are to supply apparatus of this class whose heating means 6 are'easily controlled to render the supply of liquid fuel to the heater safe by including a safety devicepreventing back-firing to the fuel tank, and to house the fuel tank in such a manner as to keep it'sc'ontents sufliciently warmed when ex osed to cold weather. f

I have accomplished the above objects by the means which are hereinafter, described andclaime'd, and which are illustrated in the accompanying drawings; in which Fig. 1 is aside elevation of my device, with parts broken awa or in section, and Fig", 2 is an enlarged detail view of the safety tank faucet, with parts in longitudinal'section. 1

The numeral 2 shows a of pipe supported fixedly on supporting standards 1, and having vertical parts 3 and 4;, the part 3 serving as a combustion chamber, and the part 4 as a flue to discharge the gases of combustion after traversing the coil 2. Fig. 3 is 5 a top plan of the coil with the parts 3 and 4 in horizontal section.

The numeral 5 denotes a hollow rectangular warming chamber whose open front end has oblique or inclined edges at 6, and 7 is a hinged cover for the opening to ride on said edges, and when down having a hasp 8 which is releasably resiliently secured on a pin 9. The upper open end of the pipe part 3 is sealed into an opening in the bottom of the chamber 5, while the upper part of the pipe part 4 traverses a hole of larger diameter 16 in the bottom of the chamber and also is fitted tightly into a hole 17 in the top of the p .coil'andcoverin-git as shown, when the coin- V chamber. r

13 is an open cup suspended on a chain 11 within the pipe part 3 at a desired height therein, the upper part of the chain traversing the hole 10 in the low front wall of said ohamher and having a ring 12 by which the chain may be moved to raise or lower the cup 13. Within the cup is placed a pad of asbestos 14:-

Within the chamber 5 is mounted a fuel tank 18 having in its top a removable filler cap 19, for admitting liquid fuel.

A faucet device having alined tubes 20 and.

top pipe part 3 and into the com 1929. Serial no. aszisv'.

23 has .an intermediate valve-chamber 21 whose valve is controllable manually by means of a stem and wheel'member 22. This faucet is mounted on the front wall of the tank 18 and, mounted on the front end of the pipe section 23, as shown in sectionin Fig. 2,- isa small chamber 2& having a'depending bored nipple 25 positioned to deliver liquid fuel in drops downwardly throu h the open ustion c'up 66 '13 to saturate the pad 14 therein, the "latter serving as a wick. The fuel impregnating said Wick can be ignited by dropping abit ofblazing paper thereinto, or otherwise. 1 y d I To prevent back firin of the fueland into the tank 18, have supplied in the upper part of the chamberQ l a hemispherical valve-"seat 26 to fit a ball valve 28. The numeral denotes an interiorlv threaded closure-edgier h the upper end of the chamber 24. The numeral 29 denotes an inflammable thread or cord having its ends clamped betweenjsaid capQrZ and the upper edge of the chamber 24, the" middle part of the cord being Slack enough to "support thereon-the ballsvalve 28" its upper position clearing the delivery ripening or" passage of the faucet, In cas'e'of [aback firing of the dropping fuel fir'e entering the nipple will instantly consume the cord 29;the ball dropping 'to close the faucet." It has 89 been found that when such a heater becomes warmed up considerably iindersome eorid i tions of use, such back firing may oc an's-11a cause explosions and the berm-agar buildings orhousings when no one is near to prevent it. This device thus works automatically 'as a safetymeans.

A hover canopy canjb'e combined withthe binat-ion is to be employed as a hover or 90 brooder for chicks. My device can be: easily adapted to; be used as ai tank heater The hinged flap 7 being sews; a Circulation ofwa'rm airis established in "the coil 2; its vertical par-ts and the hdusing 5, to warm the liquid fuel in the tank 18 when submitted to cold. This air draft downwardly through the pipe part 3 also directs the sam dew-n: wardly lessening'liabi'lity of back The p (2111213? may have: projections '15: to fleep it centered in the pipe part 3. The hole 16 supplies fresh air for combustion, and the products of combustion are exhausted through the pipe part 4.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:

1. A device of the character described, comprising in combination, a coil of pipe having vertical open end parts which serve respectively as a combustion chamber and a discharge flue, a burner mounted in spaced relation in said combustion chamber, a hollow housing one end of which is in communication with said combustion chamber, the other end traversed by said flue, and having an air inlet in its bottom adjacent said flue, a closed tank for liquid fuel in said housing, and valve-controlled means for delivering liquid fuel from said tank through said combustion chamber into said burner.

2. A device of the character described, comprising in combination, a coil of pipe horizontally arranged and having vertical parts of which one serves as a combustion chamber, the other serving as a flue, a hollow housing having one open end with a movable closure therefor, said combustion chamber being in communication with said housing near its open end, said flue traversing the other end of said housing to discharge above it, said housing having in its bottom surrounding said flue an inlet opening, a cup suspended in said combustion chamber adjustably removably and having an inner wicking liner, a closed tank for liquid fuel in said housing and spaced from its side walls, and a valve-controlled faucet on said tank adapted to adjustingly deliver the fuel by drops through said combustion chamber into said cup.

3. A device of the character described, comprising in combination, a horizontally disposed coil of pipe, means for supporting it in spaced relation from a supporting surface, said pipe having vertically disposed parts, of which one serves as a combustion chamber and the other as a discharge flue, a hollow housing supported on said parts, the combustion chamber termination in communication with one end of the housing and the flue traversing the other end of the housmg, the housing having an inlet port'in its bottom encircling said flue, a burner for liquid fuel mounted in and with spaced relation to said combustion chamber, and a liquid fuel tank mounted in said housing and having adevice to deliver fuel to the burner.

4. device of the character described, comprislng in combination, a coil of pipe having vertical parts which serve respectively as a combustion chamber and as a flue, a cupped burner suspended removably and for vertical adjustments in and in spaced relatum to the inner walls of the combustion chamber, a hollow housing one end of which is in communication with said combustion chamber, its other end being traversed by said flue and having in its bottom an air inlet, a closed tank within said housing intermediate said flue and the communication with the combustion chamber and having a manually controlled valvular faucet provided with a terminal chamber having a valve seat and nipple leading therefrom to deliver liquid fuel downwardly through the combustion chamber into said cupped burner, said terminal chamber extending vertically above the faucet passage to said valve seat and nipple, a closure cap for the open upper end of said terminal chamber, a combustible filament supported across the upper part of the terminal chamber, and a ball valve supported in said chamber upon said filament above the faucet passage whereby combustion of said filament allows the ball to drop and close said valve seat.

5. In combination, a coil of pipe having open ends, heating means in one end of the pipe, a housing in communication with this 0nd of the pipe, the other end of the pipe traversing the housing to open without it and the housing having an air inlet, a supply container of liquid fuel, and a manually controllable valvular delivery device in communication with said container and adapted to deliver liquid fuel therefrom into said heating means.

In testimony whereof I affix my signature.
